COTTON-HOE.

SPECIFICATION forming part of Letters Patent No. 461,133, dated October13, 1891.

Application filed March 20, 1891. Serial No. 385,740. (No model.)

To @ZZ whom t may concern.'

Se it known that I, WILLIAM B. SMITH, of Atlanta, in the county ofFulton and State of Georgia, have invented a new and useful Improvementin Cotton-Hoes, of which the following is a specification.

Myinvention relates to an improvement in cottoirhoes in which adisk-fender acting as a traction-wheel actuates a thinner or cut-tertransversely to the row or path in which the plow travels, thetraction-disk and thinner or cutter forming an attachment for plows ofordinary structure.

A practical embodiment of my invention is presented in the accompanyingdrawings, in Which- Figure I is a view of the plow in side elevationwith the attachment secured thereto as in use. 2 is a top plan View ofthe same. Fig. 3 is a horizontal section through line xx of Fig. l. Fig.I is an enlarged sectional View of the joint at the plow-beam. Fig. 5 isa view in detail of one form of thinning or cutting disk, and Fig. 6 isa view in detail of another form of thinning or cutting disk.

A represents a plow-beam, to which a ploW c, of any ordinary or desiredform, may be attached.

To one side of the beam A one member B of the attachment connection issecured and is provided on its lower face With a rounded projection b,adapted to seat in the concave face b of the other member B of theconnection. The lower face of the member B is provided with a recess b2for the reception of the upper end of the hanger C, to which theoperatin g parts of the attachment are secured. The faces of theprojection b and seat b are roughened to prevent slipping, and a boltextending through the hanger C and the members B and B serves to lockthe parts in the desired adjustment. It is obvious that the concave seatmight be made in the member I3 and the rounded projection on the memberI3.

The combined traction disk and fenderI) is made dislrshaped, and isint-ended to present its convex side toward the row when in operation.Its edge is notched toafford it a better hold upon the earth inproximity to the row, and it is provided upon its outer face with anannular series of teeth d, adapted toengage and Arotate a pinione,secured in a shaft E, as Will hereinafter be more particularly1 referred to.

The hub d of the traction-disk is provided with a taper bore adapted tofit a taper spindle F. The spindle F has a bore f extendinglongitudinally therethrough, and has a concave seatf on its inner end.The spindle is secured to the hanger by means of an L-shaped extensionf2, formed integral with or fixed to the spindle at one end, and at itsopposite end provided with an attachment precisely similar to that shownby the parts B B', the part corresponding to B being provided with arecess f3, in which the lower end of the hanger is secured.

A horizontattframe G, having a general U- shaped form, extends from theinner end of the spindle around the edge'of the tractiondisk and back tothe outer end of the spindle. The said frame G is provided at the innerend of the spindle with a rounded projection g, adapted to engage theconcave seat f in the end of the spindle and is provided alongl itsouter branch with a bearing gfor the reception of the operating-shaft Ecarrying the pinion c. The portion g2 of ,the frame G which extends fromthe bearing g to the outer end of the spindle preferably extends up andover the pinion e, as shown in Fig. I. The ends of the frame G aresecured to the spindle and the traction-disk is secured on the spindleby means of a bolt II, which extends through the spindle and throughboth ends of the frame.

The direction of the shaft E is such that the cultivator-disk which itcarries upon its rear end occupies a position substantially transverseto the row or the path in which the plow travels. The cultivator-diskmay be either a series of arms '11 radiating froma hub I, as shown inFig. 5, or it may consist of a curved blade c" extending partiallyaround the periphery of the disk and secured to the hub I by arms i2, asshown iu Fig. G. In either case the disk is removably secured to a hub efixed on the end of the shaft F., the adjacent faces of the hubs I I',and the hub e on the shaft being roughened or serrated to preventslipping. The face of the hub e may be provided with screw-threadedstuds disk either athinner or acutter, and the arms c 'L' or blade 7."will cut across the row at intervals, depending upon the number of armsi or the interval between the ends of the cutting-blade i. The latterhaving a cuttingedge on the front of its rim Will alternately cut With ashearing cut, and then skip as the plow advances.

What I claim is- 1. In a cotton-hoe, a traction-disk and means forattaching it to a plow or the like, a frame secured to and carried bythe spindle of the traction-disk, and a cultivator-disk mounted in theframe and geared t0 the traction-disk, the cultivator-disk having arotary movement in a plane transverse to the path of the traction-diskand having its cultivating-blade arranged to act at intervals,substantially as set forth.

2. In a cotton-hoe, the adjustable hanger, the adjustable frame andspindle secured to the hanger, the combined fender and traction diskmounted on the spindle and having an annular gear on its face, a shaftjournaled in the frame and having a pinion adapted to gear with theannular gear, and a cultivatordisk removably secured to the shaft,substantially as set forth.

WILLIAM B'. SMITH.
